It seems that the "polar vortex" is not finished with Ontario yet.
Forecasters are warning of cool Arctic air that will swing through central Canada next week and hit the Great Lakes region hardest, The London Free Press reports.
It will plunge parts of Ontario into fall-like temperatures, with highs in the London area expected to hit around 23 degrees Celsius.
Though it won't freeze the Great Lakes, it could mean that Ontario sees temperatures that are about five to 10 degrees Celsius below normal, Sault Ste. Marie's Local 2 reports.
However, not everyone agrees with the weather's characterization as a "polar vortex."
National Weather Service meteorologist Dan Petersen told Reuters that it's a "wintertime phenomenon."
